Descriptive statistics

Description

---

This algorithm allows you to do calculations in statistic descriptive in one way very easy, because you only need paste the data and run the script

What can calculate?:

Information	Tables with	Figures	Examples
Min value	Absolute Frecuency	Histogram	See Figures
Max value	Mark of class	Frequency polygon	Results - Resultados
Old range (Range)	Relative Frecuency	Ascending Ogive
Range (New Range)	Cumulative Absolute Frequency	Descending Ogive
Size of interval class		Ogive Ascending and Descending
Old amplitude (Amplitude)		Circle Dragram
Amplitude (New Amplitude)
Old excess (Excess)
Excess (New Excess)
Maximun sample size
Mark of class
Simple frequency

Requeriments

---

You must have a version of python as indicated below or greater, but but this does not support python 3x

• python 2.7x
  • Windows : Download
  • Debian / Ubuntu: sudo apt-get install python2.7
• matplotlib
  • pip install matplotlib
  • Debian / Ubuntu : sudo apt-get install python-matplotlib
  • Fedora / Redhat : sudo yum install python-matplotlib
• numpy (This is included in matplotlib)
  • pip install numpy
• astropy Optional Instalation
  • pip install --no-deps astropy

How install pip?

• Windows
• Linux or windows, after python install you must type in cmd or terminal easy_install pip
• Installation documentation

How use the algorithm?##

---

First Step

Copy the text of estadistica.py in any text editor, in windows for example you could use notepad, then paste it and save the file as any_name.py, with .py extension.

Now follows these steps:

You must write the information within self.data, if you need exact calculation, you should add a decimal value in any number, example the first number is 60, change it by 60.0 and then the rest will be changed automatically when you run the script

You can add:

• numbers
• spaces
• jump of lines
• dot for decimals (decimal numbers)

Warning: Don't Use commas ,

Example:

self.data = """
60 66 77 70 66 68 57 70
      66 52 75 65 69 71 58 66 67 74 61
63 69 80 59 66        70 67 
78 75 64 71 81 62 64 69 68 72 83 56
65 74 67 54 65 65 69 61 67 73 57 62     67 68 63 
67 71 68 76
   61 62 63 76 61 67
   67 64 72 64 73 79 58 67 71 68 59 69 70
66 62 
63 66

"""

Optional Step

if you want see a pretty tables:

sees the penultimate line of code and change it.printme(0) by it.printme(1), because 1 enables astropy tables, which are nice, however if you cant install astropy could use 0 by default.
